Example code for forms in bootstrap
1. Basic form: For the basic form, Bootstrap did not do much customized effect design, only customized the fieldset, legend, and label tags in the form.


fieldset { min-width: 0; padding: 0; margin: 0; border: 0; } legend { display: block; width: 100%; padding: 0; margin-bottom: 20px; font-size: 21px; line-height: inherit; color: #333; border: 0; border-bottom: 1px solid #e5e5e5; } label { display: inline-block; margin-bottom: 5px; font-weight: bold; }
2. Horizontal form class name “form-horizontal”




1.Input box input: for To make the control style correct in various form styles, you need to add the class name "form-control". Each form control below can be added.

ea:添加了类名“form-control”类名,则无需设置cols属性。

nbsp;html> <meta> <title>表单控件——表单控件大小</title> <link>


.radio, .checkbox { display: block; min-height: 20px; padding-left: 20px; margin-top: 10px; margin-bottom: 10px; } .radio label, .checkbox label { display: inline; font-weight: normal; cursor: pointer; } .radio input[type="radio"], .radio-inline input[type="radio"], .checkbox input[type="checkbox"], .checkbox-inline input[type="checkbox"] { float: left; margin-left: -20px; } .radio + .radio, .checkbox + .checkbox { margin-top: -5px; }


.radio-inline, .checkbox-inline { display: inline-block; padding-left: 20px; margin-bottom: 0; font-weight: normal; vertical-align: middle; cursor: pointer; } .radio-inline + .radio-inline, .checkbox-inline + .checkbox-inline { margin-top: 0; margin-left: 10px; }
5.控件大小:类名input-sm:让控件比正常大小更小;类名input-lg:让控件比正常大小更大;宽度配合Bootstrap的网格系统


.input-sm { height: 30px; padding: 5px 10px; font-size: 12px; line-height: 1.5; border-radius: 3px; } select.input-sm { height: 30px; line-height: 30px; } textarea.input-sm, select[multiple].input-sm { height: auto; } .input-lg { height: 46px; padding: 10px 16px; font-size: 18px; line-height: 1.33; border-radius: 6px; } select.input-lg { height: 46px; line-height: 46px; } textarea.input-lg, select[multiple].input-lg { height: auto; }
